JAMES W. RENEAU, OF HOUSTON, TEXAS.

CAR-WHEEL LUBRICATOR.

SPECIFICATION forming part of Letters Patent No. 527,447, dated October16, 1894.

To all whom it may concern:

Be it known that I, JAMES W. RENEAU, of Houston, county of Harris, Stateof Texas, have invented certain new and useful Improvements in Oar-WheelLubricators, of which the following is a specification, reference beinghad to the accompanying draw- 1ngs.-

The object of my invention is to produce an improved lubricator for carwheels, one which can be readily operated while the wheels are inmotion, or at other times, and which, feeding only when it is desired,avoids leakage.

In the accompanying drawings, Figure 1 is a perspective view of two carwheels with my device attached. Fig. 2 illustrates in perspective one ofthe lubricating boxes and axle boxes with parts of the walls brokenaway. Fig. 3 is a central vertical section thereof through the feed boxand contiguous parts.

Referring to the figures on the drawings: 1 indicates an air tightcylinder having, preferably at opposite ends, reduced parts 2 toaccommodate springs 3. The springs are seated in the ends of the reducedparts at one end and at the other bear against the piston heads 4:,respectively. The springs tend normally to urge the piston heads towardeach other. For driving them in the opposite direction, I employ a powerof compressed air communicated, as through a pipe 5, to the pistons.When the air is forced into thecylinders the pistons are urgedoutwardly. When it is exhausted, the springs force them in the oppositedirection.

For controlling the pneumatic pressure in the cylinder 1, I employ anysuitable mechanism communicating with the cylinder through the pipe 5,as for example, an air brake pipe 6. I do not, however, limit myself tothe employment of this particular means, because a special pipe may beemployed, or any suitable mechanism may be substituted therefor.

7 indicates an axle box and 8 the axle.

9 indicates a lubricator box or reservoir designed to contain a suitablelubricant.

10 indicates an interior wall in the lubricator box through which a feedoutlet opening 11 is made and within which opening is preferably closelyfitted a feed box 13 carried upon the end of the piston rod 14, whichmay be bent to bring it in suitable relations with the pistons. By thereciprocation of the piston the feed box is caused to move back andforth through the opening 11 into and out of 1 ApplicationfilerlDecember19,l893. SerialNo. 494,018. (NomodeL) feed box 13 ispreferably employed so that the box is thoroughly cleared after eachfeeding operation.

I do not confine myself to the details of con struction herein shown anddescribed, but reserve the right to modify and vary the same at willwithin the scope of my invention.

What I claim is- 1. In a lubricator, the combination, with a reservoirand a reciprocatory feed box, of a pneumatic cylinder, means forconveying pneumatic energy thereto, a piston and piston actuating springwithin the cylinder, and mechanism operatively connecting the pistonwith the feed box, substantially as specified.

2. In a car axle lubricator, the combination, with a car, of areservoir, movable feed box, pneumatic pressure supply pipe, cylinder,pipe connecting the interior of the cylinder with the supply pipe, apiston within the cylinder, and mechanism connecting the piston with thefeed box, substantially as specified.

3. Ina lubricatingapparatus, the combination, with a pneumatic cylinder.and means for supplying the same with pneumatic energy, of a pluralityof lubricating reservoirs and feed boxes, a plurality of pistons withinthe cylinder and mechanism operatively connecting the feed boxes andpistons, respectively, substantially as specified.

4. In a lubricating apparatus, the combination with a pneumaticcylinder, of a plurality of pistons therein, a plurality of reservoirsand feed boxes, mechanism operatively connecting the feed boxes andpistons, respectively, means for supplying the cylinder with pneumaticenergy between the pistons to actuate them simultaneously in onedirection, and automatically actuating mechanism adapted to actuate thepistons in the opposite direct-ion, substantially as specified.

In testimony of all which I have hereunto subscribed my name.

JAMES w. RENEAU.
